-3 ≤ 6x - 6 < 39 (seperate into two inequalities)
6x - 9 ≥ -3
6x - 9 < 39 (solve the inequalities)
x ≥ 1
x < 8 (find the intersection)
x ∈ { 1 , 8 }
Answer:
Step-by-step explanation:
<u>As per similarity, the ratios of corresponding sides are same:</u>
- x/120 = 65/50
- x = 120*65/50
- x = 156 ft
Answer:
b. We are 95% confident that the proportion of coworkers who went on a vacation last year away from home for at least a week is between 50% and 66%.
Step-by-step explanation:
A confidence interval at the level of x% for a proportion being between a and b means that we are x% sure that the true proportion of the population is between a and b.
In this problem, we have that:
95% C.I is (0.5, 0.66)
Interpretation: 95% confident that the true proportion is between 0.5 and 0.66.
The correct answer is:
b. We are 95% confident that the proportion of coworkers who went on a vacation last year away from home for at least a week is between 50% and 66%.
For question 40 the answer is B
Answer:
(4,0)
Step-by-step explanation:
(5,3) (1,3)
You need to subtract from the x axis on both coordinates and the y axis in both coordinates.
(5-1) (3-3)
(4,0)
I also checked on a graph as well, so it's correct.
